dear R wizards: environment-related programming question:
myformula = y ~ a*x^2+b*x+c
d= data.frame( x=rnorm(20), y=rnorm(20) )
cat("\nunconstrained works: \n");
nls( myformula, data=d, start=list(a=1, b=1, c=1), trace= TRUE)
cat("\nconstrained works: \n");
b=1; nls( myformula, data=d, start=list(a=1, c=1), trace= TRUE); rm(b)
cat("\nbut how do I pass a local parameter into my formula? \n");
f = function(c) nls( myformula, data=d, start=list(a=1, b=1), trace= TRUE)
f(c=1);
advice, as always, appreciated. /iaw
